Referring to-the accompanying drawings and particularlyto-Figs. l and..l.0,;thereference chars-- acter l I generally indicates a vending machine-or thekind in whichthe --present =coin-controlled mechanism is incorporated. Vending machines of this character include a cabinet I 2 having a window opening I3 through which a plurality of stacks M of merchandise may be viewed. The stacks of merchandise are contained within racks, generally indicated at l5, each of which includes a plurality of pivotally mounted shelves or platforms 16 disposed in spaced relation one above the other to provide a plurality of compartments each adapted to contain one piece of merchandise.

Inasmuch as the specific construction of the racks and the manner of mounting the platforms and controlling their selective function to dispense merchandise is fully disclosedand claimed in the aforementioned Stoner Patent No. 2,324,040, the specific details of construction will not be repeated herein. It is sufficient to note at this time that upon manipulation of manually actuable means associated with each rack, one of the platforms or shelves l6 therein is tilted so as to permit the piece of merchandise supported thereby to drop into a dispensing chute for delivery to a receiving tray l1 provided on the front side of the vending machine.

The manually operable actuating mechanism effective to vend a piece of merchandise is generally illustrated in Figs. 9 and 10. This mechanism normally is held against manual operation by means of a coin-controlled mechanism Hi suitably associated therewith and mounted on one side of the bank of merchandise racks I5, which mechanism embodies the features of the present invention and will be described in detail hereinafter.

It is to be noted, however, that the coin-controlled mechanism 18 is of a kind adapted to selectively release and render operable any one of the plurality of manually operable merchandise dispensing mechanisms associated with each of the racks i5. Operation of the merchandise dispensing mechanisms is accomplished by the customer grasping a selected one of the reciprocal plungers l9 extending outwardly of the front face of the vending machine casing 12. The construction and operation of the vending mechanism im mediately associated with each plunger 39 is such that it may be adjusted readily to adapt the particular rack associated therewith for containing and dispensing merchandise having a value of five cents or ten cents.

Upon referring to Figs. 9 and 10, it will be observed that each plunger l9 carries a vertically disposed actuating rod 20 which extends upwardly therefrom and is suitably guided in a slot provided in the upper flange 2! of a guide channel arranged on the front side and adjacent the lower ends or the racks l5. Inasmuch as the construction of the operating mechanism associated with each rack is identical, with variations in the mechanical adjustment of certain parts thereof, the following description concerns itself with one such mechanism only.

A journal pin 22 provided closely adjacent to the plunger l9 is firmly secure at its ends in the upper and lower flanges of the channel mentioned hereinabove and it carries a set of crank arms 23, one located above the other and suitably spaced apart. Each crank arm has a forwardly extending ear 24 suitably apertured to receive a pintle pin 25 for pivotally connecting the ends of said ears, one to each of a set of draw bars 25 which extend longitudinally across the front of the guide channel.

In the instant vending machine, the arms 23 in each set are disposed in horizontal rows and a draw bar 26 is connected with all of the crank arms in each horizontal row. The crank arms mounted on any one of the journal pins .22 are adapted to be operated either singly or jointly. Each crank arm 23 has an enlarged portion disposed on one side of the journal pin 22 which includes a shoulder 27 normally disposed closely adjacent to the vertical rod 215 of the related plunger l9. Triggers 28, one associated with each crank arm 23, are each pivotally mounted at one end on the related pintle pin 25, and each has its other end suitably shaped to provide a downwardly extending lug 28 which normally lies in the path of the associated vertical rod 29. Springs 3!. anchored at 32 on each crank arm 23, have one end engaged in an car 33 formed along one edge of the related trigger 28 and extending upwardly through an arcuate slot 34 in the related crank arm 23.

Upon referring to Fig. 9, it will be observed that there are two crank arms 23 and triggers 23 constituting each set of operating mechanisms and, for purposes of description, they are identified herein as a and b. As there shown and illustrated in Fig. 10, the lugs 29 on all of the triggers 28 of the lower or a row of crank arms 23 are disposed in the path of the vertical rod 2!] so that when the related plunger is is pulled outwardly to operate the vending machine, the associated crank arm will be swung about its journal pin 22, thus shifting the draw bar 26 connected therewith longitudinally across the front of the machine.

Each of the crank arms 23 constituting the set of crank arms associated with the merchandise rack at the extreme right hand end of the machine, as viewed in Figs. 9 and 10, has an arm extension 35 carrying a knob or roller 38 which coacts with the coin-controlled mechanism Hi. This coin-controlled mechanism is ffective normally to prevent actuation of any set or sets of the actuating crank arms 23.

The instant vending machine is intended to vend merchandise having different values. Accordingly, the upper or h set of crank arms 2-3 are adapted to be selectively adjusted for engagement by the vertical rod 24' when the related plunger I9 is pulled outwardly. Thus, it will be observed, upon reference to Figs. 9 and 10, that the upper crank arm 23 also has its trigger 28 positioned for engagement by the vertical rod 23 when it moves outwardly. Accordingly, outward pulling of the plunger 19, associated with the right hand rack shown in Fig. 10 will cause operation of both crank arms 23 provided, of course, that the coincontrolled mechanism has been conditioned by the insertion of the proper coin. Still referring to Fig. 10, the upper crank arm 23 associated with the second merchandise rack is selectively conditioned so that movement of the plunger 19 associated therewith will impart rotation to the lower crank arm 23 only, provided again, that the coincontrolled mechanism has been conditioned to permit such actuation upon the deposit of a coin or coins of the correct denomination.

The coin-controlled mechanism H; which embodies the features of the present invention is designed to effect an unlocking of the selected merchandise dispensing mechanism upon the insertion of one or more coins of predetermined denominations, so as to render the dispensing mechanism actuable to vend an article of merchandise of a value corresponding to the number or denomination of coins deposited. In the presend instance, the coin-controlled mechanism. l8

is constructed' to accommodateinve-cent and ten cent coins;

Suitable. means is provided thearea. of said rivets to maintain the. plates, inspaced relationship with the distance between .them beingslight- 1y. greater than the thickness of thecoins for. which the mechanism isdesigned. In..the.--pres=- ent disclosure the; space between the; plates: .42 and 43 is of a sizeto correspond. to theithickness of a. fiveecent coin; The space-betweenthe plates 43' and; 44 is: of a: size to; correspondlsubstantially to the thickness of a ten-cent coin.

The. upper. margin. of. the inside. plate 43 is offset inwardly to. defineta fiangej49 to. which. is attached. a coin. mechanism 5.1-1.

This coin mechanism 5| is of standard construction and because it forms no;par t otflthe present. invention, it is not believed. to banecese sary to describethe same in great detail. It shouldbe noted, however, that said coin mecha: nismwill include the. usual magnets (notshown); for detecting fraudulentcoinsand a-jam-release mechanism includinga movable. plateand-a trigger. 52; actuableto release said jamerelease mechanism. The specific. means provided. for. actuating said-jam-release trigger will be; described in detail hereinafter.

It should. be sufficient to note at thistime that when a coin is deposited. in a ,coinreceivi g: Slot. ed i e Vendi aghme ab n ts dt coin will move-downwardly through aitrough fid (Fig. 6) into the coin: mechanism 51L Should the. coin beof a. denomination: for: which the coinimechani'sirris not conditione'cl'to receive, .said coin will,. in a. manner customary. with such devices', enter intcr either oneof: a pair. of: return chutes-1:55 and-1 55 from WhlGhIit' is discharged intmasubstantially vertical duct-51: (Fig. 2 provided ionthe outsidefaceof theoutside plateAZ The lower. end oi the duct .5? has. an. inclined surface 58 whichaextends. through an openingzSB in both plates 42: and l3iso as to-direct the coin; into a coin-return: ledge 61 provided on the front of the; vending: machine. cabinet.

This ear isilocatednsub-i stantially intheareaof thetriggerear 8.5211301. a purpose to be described. presently.

The inside plate 43 of th'e coin-.-controlled mech anism is provided-with a plurality of horizontally I disposed verticallyspacedslots'81,82; 83 and 84,

eachto receive for freesliding movement therein aforwardly projecting portion of eitherone of'a pair-of slide p1ates85 and86. (Fig; 8). The slide plate 8.5 isfabricated from a piece of sheetmaterial substantially to the configuration illustrated in Fig, 8. As. there shown, it has a, flange. 81. formed onone of its edges andbent substantial; lit at. right. angles thereto which flange projects through the slot. 81. A; secondflange 88. formed along another edge of said. plate 85 extends throughthe slot .83... A thirdflange 8.9..formed along. the edge .of said platev having the flange 8.8 .thereon, but. adjacent. theroppcsite i end thereof, iseot sufficient height to project. slightly throughahorizontally extending slots!- (Fig. 1.2) provided-in the. inside plate .43.v Like slots. 92. (Fig-.10): and. 93 -.(Fig. -1 1) a1so= areprov-ided inv the., insid, plate 43.; Each, of these slots .have

complemental registering slots Bla, 92a and 93a, provided in the auxiliary plate 44.

The other slide plate 86 likewise is provided with flanges bent at right angles thereto, one of which, as at 94, extends through the slot 82, while the other flange 95 extends through the slot 84. The pair of flanges 81 and 94 are provided with notched recesses 96 and 91 each of which is adapted to receive, in detachable engagement therewith, one of the rollers 36 on the free end of each crank arm 35. Upon referring to Figs. 9 and 10, it is evident that when either one or both of the crank arms constituting a set of crank arms journaled on the vertical pins 22, is rotated about its journal, the corresponding slide plate or plates will be shifted in a horizontal plane substantially from the position illustrated in Fig. 8 in full lines into the position there illustrated in dotted lines.

Sliding movement of said slide plates normally is prevented in the absence of the proper coin or coins having been inserted in the coin-controlled mechanism. Means to prevent such sliding is provided in the form of stop lugs MI and I02 (Fig. 8) one extending from an edge of each intermediate wall or bight portion I03 and I04 of a pair of substantially U-shaped locking members I05 and I06. The locking members are fashioned from sheet stock and they have their substantially parallel legs pivotally mounted adjacent their free ends upon the vertically disposed journal pin 73. Each of these U-shaped locking members has a leg extension of I01 projecting beyond the journal pin I3. Springs I08, one connected at one end to each of the other side wall portions and at their other ends to a flange I09 on the coin-controlled mechanism, normally hold the U-shaped locking members firmly against the face of the inside plate 43 so as to hold their respective lugs 10! and I02 projected into the space between the plates 42 and 43.

Obviously when the stop lugs IOI and I02 are located in the path of the slide plate 35, said slide plate cannot be shifted out of the position substantially as shown in full lines in Fig. 8. Such limited movement as is permitted of the slide plate 85 while the lugs are so positioned'is obtained by reason of the clearance between said lugs WI and I02 and shoulders III and H2 on said slide plate.

Sliding movement of one or both slide plates 05 and 86 is necessary to permit actuation of the vending operating mechanism described hereinabove, because each slide plate is operatively connected with the actuating mechanism through the rollers on the crank arm extensions 35. Accordingly, means is provided on both slide plates movable therewith to rock the U-shaped locking members I05 and I06 into unlocking position. The means provided on the slide plate 85 consists of a pair of cam arms H3 and H4, both of which are slideably connected to the projecting flange 81 on slide plate 85 as by means of a vertical stud or screw I IS. The stud llfiextends freely through a slot I H5 in the cam arm I I3 and aslot II! in the cam'arm H4.

Because of the slotted connection between the cam arms H3 and H4 and the slide plate 85, limited sliding movement of the slide plate may be accomplished without longitudinal shifting of the cam arms H3 and I I4. Such limited or initial sliding movement is, as noted hereinabove, limited by abutment of the slide plate edges III and H2 with the stop lugs IOI and I02. Means is therefore provided on the cam arms H3 and H4, effective when said arms are shifted a sufficient distance longitudinally, to lift the U-shaped locking members I03 and I04 so as to carry their stop lugs I 0| and I02 out of the path of the edges III and H2 to thereby permit the slide plate to be shifted longitudinally through a complete cycle of operation.

As best shown in Fig. 10 the cam arm H3 is provided with an offset cam edge I20 normally closely adjacent to the end wall of the U-shaped locking member I05. Said locking member end wall is suitably slotted, as at I2I, to receive the free end of the cam arm H3 therethrough. It should be apparent that when said arm is shifted longitudinally its cam surface I20 coasts with an edge of the slot I2I to thereby rock the looking member outwardly away from the inner plate 43. Similarly, the cam arm I I4 is provided with a cam surface I 22 (Fig. 11) adapted to coact with the edge of a slot I23, in looking member I04, through which said cam lever extends. When the cam arm I I4 is shifted longitudinally during operation, the U-shaped member I06 is rocked about its pivot I3 sufliciently to carry its stop lug I02 thereon out of the path of the slide plate 85.

The specific mode and manner of operation and function of the slide plate 85, and of the related cam arms H3 and H4 carried thereby, will be more specifically referred to hereinafter. It is sufiicient to note at this time, however, that the free ends of each of the cam arms H3 and H8 are provided with fingers I20 and I2! respectively, which fingers project through the related slots 02-92a and 93-93a respectively, in the plate assembly.

The projecting flange 88 on the slide plate 85 also carries a cam arm I23 (Fig. 12) suitably formed with a cam edge I 29 adapted, under certain conditions of operation, to coact with the end of a slot I3I provided in the end wall or bight portion of a U-shaped member I32 pivotally mounted about the journal pin I3. The arm I28 also has a projecting finger I33 which extends freely through the registering slots 9I-9Ia in the plate assembly.

The operation of the mechanism insofar as it has been described hereinabove is substantially as follows:

Assuming the customer desires to purchase merchandise valued at five cents, a five-cent coin V is deposited in the coin receiving Slot 53 and subsequently comes to rest on the stop finger 62 (Fig. 8) in such position as to lie in the space between the forward edge I35 of the slide plate 85 and the projecting finger I27 of cam arm Ht. The operator then grasps a plunger I9 associated with the rack containing the merchandise selected. The plunger I9 is then pulled outwardly. This causes both crank arms 23 of the related set of crank arms to rotate about their pintle pin 22, so as to impart sliding movement to both slide plates 85 and 86. The presence of a coin V in the area between the slide plate and the cam finger serves to maintain the cam arm substantially in the position best illustrated in Fig. 11. Accordingly, the cam surface I22 on said arm H4 will coact with the slot I23 to rock the U-shaped locking member I06 outwardly and thereby carry the stop lug I02 out of the path of the slide member 85.

Advance of the slide member 85 past the withdrawn stop lug I02 would normally be prevented by the presence of the stop lug "II on the U- shaped locking member 105;. This second looking of the slide plate szmustnecessarily be eliminate'd. It is for this reason that the vending of merchandise valued at live cents requires the sliding of the slide plate-86 in addition to the slide plate 85. Upon referring to Figs. Sand 10,-it will be observed that the cam arm 553 has an upstanding pin I36 which projects into the path of the flange -54 on slide plate 85. Consequently, joint-movement-of both slide plates imparts positive forward advance of the cam arm H3, netwithstanding-its slottedconnection withthe slide plate '85. This positive forward advance of the cam arm H3, during the intervalwhile the slide plate 85'is advancing to take u 'the slach'ie5u1ting from its slottedconnection with cam arm 4 Hi, permitsthe cam surface 120 of the cam arm 53 to'enga'ge and coact'with theiendof the slot 12.5 in the .U-shaped locking member its to thereby rock the same and carry its stop lug 9 5i out of the path of the slide member -65. Such coaction of the cam surface 1:25 with the locking mere" ber IE5 is occasioned by the fact that the cam arm H3 is formed with aflat surface i3l which initiallyrides upon the surface of .auxiliaryplate 44' with the result that its free end does not fall into the registering slots QZ-Eiiwwhile its cam surface I26 is passing through the slot iii.

During the dispensing of a five-cent pieceof merchandise, the cam arm I28 also is carried through the slot 131 in its related'locking meinher I 32. However, said cam arm does not impede sliding movement .of the slide plates and does not rock the locking member Hi. This re" sults from the absence .of a coin in the path of the camarm 12.8 which allows said arm to move into the slots di llia while its cam surface E23 passes through the slot lB-i. .Upon refe ring to Fig. .12, it will be observed that as the slide plate .85 advances, the edge [38 of itsfiange as is engaged by a shoulder 39 on one-edge of the earn arm 28 to thereby limit movement of the cam arm into the registering slots 9-l' ia. CQonsequently, the cam surface 12%! on said arm 23 rides beneath the end of the slot 'i3i without imparting any'rocking movement to thew-shaped member E32.

The purchase of a ten-cent piece of merchandise may be efiected by depositing two five-cent coins in the coin-controlled mechanism. Under such circumstances, both coins V and N will rest substantially .in the positions shown in Fig. The presence of a .iivezcent coin .V in the lower most position illustrated will act upon the asso ciated cam arm and locking member 5 55 in the manner described hereinabove.

The presence of the-second coin N in the space between theforward edge Hi5 of the slide plate ssand the cam armfinger will hold said arm in'the position substantially as illustrated in'Fig. :10 .totherebypreventsaid arm. from droppinginto registeringslotsszeta when it is-advanced. Accordingly, when the operator pullsa plunger corresponding .to a stack of merchandise of the value of ten cents only the bottom one of the two crank arms 2310f the related set of crank arms is actuated. Actuation of the lower-crank arm (-0.) in said set of crank arms imparts sliding movement to the slid-eplate 85 only. The slide plate B2] remains stationary.

Initial sliding of the slide plate 5.5 is effective .to take up. the slack-resulting from the slotted connection -.between said :slide :plate and the .cam arms 5'3 andi iii; Because both of said arms are now hel'd'in what might be termedan efiective position, owing to the presence of a coin beneath each of saidarms,the cam surfaces I29 and i2: respectively, of said arms are effective to rock both U-shaped-locking members [65 and [06 sufficiently to withdraw the stop lugs Hit and 62 out of the path of the slide plate 85. The slide platefiimay nowbe advanced the entire distance required to effect vending of the merchandise selected.

The coin-controlled mechanism is adapted also to permit the vending of merchandise having a value of ten cents upon the deposit of a ten-cent coin. In such instance, the ten-cent com .1) comes to rest in the space between the inside plate 43 and the auxiliary plate 44 and onthe blade 1| formed. on the end of the bracket 12 journaled on pin 13. This structure is best illustrated in Figs. 10 .and .12. When a ten-cent coin is held in the manner aforesaid, it is located between .the forward edge .of the flange 89 on slide plate ;8.5 and the projecting finger I33 of the :cam arm 128 (Fig. 12). Only the slide plate mustbe advanced in order to unlock the vending mechanism much in the same manner as when two five-cent coins were deposited. In this instance, however, the ten-cent coin holds the cam arm I28 in a position to cause its cam edge I29 to coact with the end of the slot l3! in the locking member .132 when the slide plates are advanced. This engagmentrocks the locking member 132 about itspivot13.

It should be noted that the lockin member +3.2 does not have a stop lug of the kind carried by the other lockingmembers I05 and H16. The locking member 132 is provided with a bailshaped extension I4! which has its intermediate portion bridging and resting against the rearwardly extending .legs I01 .formed integral with the locking members I05 and IE6. As a result of this mechanical association between thethree lockingmembers, rocking-of the looking member I32 rocks the locking members I05 and H35 to thereby withdraw their lockin lugs in! and I 02 out of the path of the s1ide'85. Consequently, theslide 8.5 may be shifted through its-entirestroke to permit the vending of the piece of merchandise of the value of ten cents.

In each instance, operation of the coin-controlled mechanism described hereinabove, either by the deposit "of one or'two five-cent coins or of a ten-cent coin, is effective to deposit said coinorcoins in-a coin receptacle contained within the vending machine. Thisacceptance and deposit of the coins is accomplished by providing an outwardly offset portion J42 in theouter plate 432. Such ofisetting of the portion hi2 provides a relatively wide vertically disposed coin-receiving chamber [4-3 into which the'coins carried forward by the advancement of the slide plate-B5 are deposited. Coins entering said chamber fall through the open bottom thereof into a coin receptacle provided within the vending machine.

Vending of merchandise having a five cent value, upon the-deposit .in the coin-controlled mechanism of a ten-cent coin, is readily accomplishedby the instant structure which is associated with means to return afive-cent coin to the customer, as change. To this end, the suitable change 'coin discharge mechanism, provided in thew/ending machine,is operatively assoicated with the slide "86. Asbest shown in Figs. 6,13 :and 15, the projecting flange v .on the slide plate 585 is 'apertured-to receive "a pin 15! firmly secured therein. A bracket, generally indicated in a horizontal plane and is suitably slotted, as I55, to receive the pin I5I therethrough. The bracket 552 also includes a substantially vertically disposed horizontally elongated platelike portion 555 which is disposed Wholly above the horizontal flange I53 and is guided for longitudinal sliding in a U-shaped bracket I56 mounted on the face of the auxiliary plate 44.

In order to operate the change delivery mechanism to be described presently, the bracket I52 must be slid longitudinally as an integral part ofv the slide plate 85.

Durin machine operation involving longitudinal shifting of the plate 85, in instances where no change need be returned to the operator, the pin I5I is conditioned, in a manner to be described presently, so as to slide freely in the slot I54 without imparting any sliding movement to the bracket I52.

Such releasable locking together of the slide plate 86 and bracket I52 as is required for the different modes of operation is best effected by providing a latch I51 on the upper face of the horizontal bracket portion I53. The latch I51 is pivotally secured at one end to said horizontal portion, as at I58, and its free end is held against unlimited displacement by a .pin and slot connection I59. Normally, a shoulder I6I provided on one edge of the latch I151 is held in engagement with the pin I5I by a tension spring 552 associated therewith. Obviously, longitudinal shifting of the slide member 86 while the latch I51 remains engaged with the pin I5I will cause said bracket I52 to be carried longitudinally as an integral part thereof.

The free or projecting end of the vertically disposed bracket portion I55 is provided with a notch or recess I63 which afl'ords means for operatively conecting the bracket I52 with the change return mechanism. This mechanism will be described in detail hereinafter.

In order to effect disengagement between the bracket I52 and the slide member 86 under conditions of operation not requiring the return of a coin, means is actuated to disengage the latch ifil from the pin I51. To this end, the locking member I32 is provided with a forwardly extending arm I54 which normally has one of its edges resting firmly against the inside wall 43. The

free end of the arm extension IE4 is located subi stantially in the area of the pin I5I when the slide member 86 is in its retracted position shown in Fig. 13 and said free end is provided with a cam surface I55.

When two five-cent coins or a ten-cent coin is inserted in the coin-controlled mechanism for the purpose of obtaining a ten-cent piece of merchandise, only the slide plate 85 is advanced while the slide plate 86 remains stationary. When both slide plates are shifted during the purchase of a five-cent piece of merchandise upon the insertion of a five-cent coin, the cam surface I55 is adapted to coact with a lug I55 on the free end of the latch I51 during initial advancement of the latch and its component parts. When the latching I65 contacts the cam surface I55 the latch, during initial advance of the slide plate 86, is rocked about its pivot I53 in the manner best shown in Fig. 14 to thereby disengage its shoulder I6I from the pin I5I. Consequently, the slide plate 86 is free to advance the entire distance of its sliding movement without carrying the bracket I52 therewith.

When a ten-cent coin is depositedin the coincontrolled mechanism for the purchase of a fivecent piece of merchandise, the cam arm I28 rocks the locking member I32 thus lifting the arm extension I54 sufiiciently to permit the latch lug I65 to pass freely therebeneath without disengaging the latch I51 from pin I5I. As a result, the bracket I52 moves with the slide plate 86 so as to actuate the change making mech-- anism to be presently described.

Means is provided in the instant coin-controlled mechanism to prevent a return movement of the sliding plates prior to the completion of an operating stroke. Such means prevents fraudulent manipulation of the device. This is accomplished by providing a pawl I1I on the coin-controlled mechanism, as best shown in Figs. 2 and 9. The pawl I1I is mounted for free rotation on pin I12 and is held normally with its engaging portion I13 substantially ver tical by two tension springs I14 which are connected one to each of a pair of legs I15 on the pawl I1I. Pins I15 projecting outwardly from the outside plate 52 provide means for securing the other ends of the springs in place. In the construction illustrated, the outside plate 42 has a horizontal slot I11 through which a block I'IB extends. The block I18 is firmly secured to the back face of slide plate 85, as by means of rivets E19, and its lower edge is serrated to provide teeth I8I disposed in a plane to cooperate with the engaging portion I13 on the pawl I1I when the slide plate 85 is moved during machine operation.

During operation, as the said slide plate 85 is moved to the right, as viewed in Fig. 2, the serrated edge IBI will engage the engaging portion 113 and rock the pawl in a clockwise direction, in which position the slide plate 85 can continue moving to the right. If this movement is stopped while the engaging portion I13 is still in engagement with the teeth I8I, the motion cannot be reversed to the left. However, when the stroke of the slide plate 85 has been completed to such an extent that the block I18 is carried past the pawl I1I, the pawl will again assume its normal substantially vertical position. When the stroke is then reversed, the pawl I'II will again be ef fective to prevent anything but a completed return stroke for the slide plate 85. If desired, a cover plate or shield I82 may be disposed over the pawl i1I to prevent access being gained thereto to render it inoperative.

Experience has established that fraudulent operation of coin-controlled mechanisms and subsequent vending of merchandise without the deposit of a coin may be obtained under certain conditions of misuse. One such condition arises when one side of the vending machine is struck a series of sharp blows of sufficient intensity and regularity as, to impart inertia to the locking members I05, I55 and I32. When this occurs, the locking members may be momentarily rocked about their pivots suificiently to permit initial manipulation and sliding of either or both of the slide plates 85 and 85. Once such initial sliding is obtained to a degree sufficient to carry the edges III and H2 of the slide plate 85 past the area normally occupied by the stop lugs IBI or IE2, the stroke can be completed and merchandise vended. Means is provided to prevent manipulation of the slide plate 85 under such conditions as have been described immediately hereinabove.

Referring to Figs. 2 and 9 an inertia lock, generally indicated at 2III, is mounted upon the outside face of the outer plate 42. This lock consists of a substantially flat plate 202 provided withpara'llel; ears $2113 :adiacent its. upper-- suitably srapertured. :zto :receive .therethrough a hinge pinzzll l.:-j-ournaledratits endsxinaearsimfi projectingrtoutwardly from atmoimtingcnlate 2G6 firmlysecured,.:as by"'welding,.-;to' the iaee .ofifplate 42. .Ihennounting :prlateiflfi haszitsrlowerzportion bent outwardly substantially at right angles thereto, as vat 5201, rand suitahly slottednat $1013 to permit. the :plate 172 02 to fiepend' zfi eely rtherethrough.

The" other arm 24:. of said bell-crank lever 232 is pivotally connected at 2 55 to one end of a link 246 which extends upwardly angularly therefrom and has its upper end pivotally secured, at 221, to the end of one arm 226 of a second bell-crank lever generally indicated at 2.59. The bell-crank lever 246 is pivotally mounted upon a pin 256 projecting outwardly from the plate 222 and its other arm 25! carries an adjusting screw 252 adapted to cooperate with a bearing block 253 projecting from one face of a link 25d pivotally mounted at one end on the 259. The other end of said link 2266 is suitably apertured to receive therethrough a journal 2135 for mounting a roller 256 thereon. The adjustable mounting of the link 252 relative to the bell-crank 26 3 is provided to facilitate accurate co ordination oi the coin-controlled mechanism with change vending mechanism to be described presently and which is actuated through operation of the bell crank 249.

Still referring to Fig. 3 of the accompanying drawings, the upper margin of the mounting plate 242 is bent substantially at right angles to provide an inclined horizontal flange 26!. This flange is provided with a circular flanged opening 262 of such size as to receive snugly therein a tube 263 adapted to contain a stack of five-cent pieces. A plurality of bolts 264 having suitable spacers thereon afford means for securing a bottom plate 265 on the bottom face of the flange 26! but in spaced relationship thereto. A reciprocal gate plate 266, best shown in Fig. 5, is slideably mounted between the flange 26! and underlying plate 265. This gate plate 266 is provided with a slotted aperture 261 of sufli cient size to receive relatively freely the roller 256 on the upper end of the link 254. Means is provided, preferably in the form of elongated depressions 266 and associated anti-friction balls 269 located between the gate plate 266 and underlying plate 265 to minimize frictional resistance to sliding of the gate plate.

The gate plate 266 also is provided with a cir cular opening 21! which normally underlies the tube receiving opening 262 in the fiange 26!. A similar opening 212 is provided in the underlying plate 265 but is offset to the right, as viewed in Figs. 3 and 5. lhe opening 212 communicates with an inclined chute 2'13 located therebeneath and firmly secured to the plate 242. The lower end of the chute is in direct communication with a coin passageway 214 formed in the mounting plate 242 as by offsetting a portion thereof throughout substantially its entire length.

It should be apparent at this time that when the slide bracket !52 is shifted longitudinally during the operation of the coin-controlled mechanism following the deposit of a ten-cent coin for a five-cent piece of merchandise, the bellcrank 232 is rocked about its pivot 24! to thereby pull the link 246 downwardly and rock the bellcrank 249 in a clockwise direction so as to move the gate plate 266 from a position where its coin receiving opening 21! aligns with the tube opening 262 into position where said opening 21! registers with the opening 212 to thereby deposit a single coin, in this instance, a five-cent piece, into the chute 213 for discharge through the passageway 214 and deliver it to the customer through a suitable opening in front of the vending machine.

Means is provided in the vending machine to prevent the accept-ance of a ten-cent coin, should the coin tube 263 be empty. Such means is :16 best shown in Figs. 3, 4, 6 and 7. Upon referring to Figs. 3 and 4, it will be noted that the horizontal flange 26! has slideable thereover a strap 28! formed with an upstanding finger 282 on the end disposed closely adjacent to the tube 263. This finger is provided with a relatively sharp point on its free end adapted to extend through an opening 233 in the tube wall a short distance above the flange 26!. The strap 28! is mounted for longitudinal shifting on the flange 26!, as by means of the screw and slot connections 284, and its rearwardly disposed end is turned downwardly as at 285 for a purpose to be explained hereinafter.

An ear 286 is folded upwardly along one edge of the strap 28! inwardly of the rear end thereof which car carries a lateral pin 28! that extends through a slot 288 in the upper end of a rock arm 289 pivotally secured at 29! to the flange 292 of the assembly mounting plate 242. The lower end of the arm 289 terminates a considerable distance below its pivotal mounting at 29! and is adapted to cooperate with a trigger 293 (Fig. 6) mounted on and operatively associated with the coin mechanism 5!. Upon referring to the Fig. 6 disclosure, it will be noted that the trigger 293 is formed on the upper end of a rod 294 journaled at 295 on the flange !09 of said mechanism. A spring 296, connected at one end to an oifset portion 29! of the rod 294 and at its other end to a pin 298 carried by the coin mechanism, normally holds the trigger firmly in contact with the rock arm 289 at all times.

The lower end of the trigger-rod 294 is bent substantially at right angles thereto to provide a lateral extension 299 having an inturned end portion 38! adapted to enter through a hole 392 in one of the side walls 393 of the coin mechanism 5! so as to be disposed in the path of a tencent coin passing through said mechanism.

When the coin tube 263 contains a supply of five-cent coins, the strap 28! is held in a rearwardly adjusted position to thereby hold the lower end of the rock arm 289 in position to hold the trigger 293 turned against the action of spring 296, to hold the inturned end portion 30! out of the coin passageway. As a result, ten-cent coins deposited in the coin mechanism 5! will move through their normal path of travel and be received and deposited in a position to permit actuation of the coin-controlled mechanism in a manner described hereinbefore. However, should the tube 263 be empty of five-cent coins to be returned as change upon the deposit of a ten-cent coin, the pointed end of strap finger 282 enters the tube 263 to thereby move the rock arm 289 away from the trigger and thus allow the end portion 30! to enter the coin path. As a result any ten-cent coin deposited in the coin mechanism is diverted by the end portion 39! and directed into the coin return passageway for return to the customer.

The construction of the change coin discharge mechanism and coin reject mechanism described hereinabove is such that each time the change coin discharge mechanism is actuated, the slide strap 28! of the coin reject mechanism is shifted in a direction to momentarily relieve the lower most coin or coins in the stack within the tube 263 of any pressure so that said coins may move downwardly in said tube as successive coins are withdrawn therefrom. This joint operation of the two individual mechanisms is eifected by the provision of the downturned end portion 285 I 2,5,24$ v 17 1&8 4 on the strap .28 L Upon referring to i5,':it loc'kingelement a distancesufiiciefl w h:- will be observed that vtheedowntumedxportipn draw its11oeking.;1ug qlfllro'utof the ,path of the 285, 1ies in the path otthe :gateplateiii 159 that Slide plate 35.
